The right answer is tracheids allow for efficient transport of water over longer distances.
Tracheids are conduits for the transport of raw sap (composed of water and mineral salts) to vascular plants. They are composed of a series of elongated cells. During the formation of tracheids these cells die, are emptied of their contents and are fused vertically to form a hollow conduit. The tracheids are located in the xylem, plant tissue allowing the transport of raw sap. Derived from the primary xylem (protoxylème), they have a role in the overall support of the plant.
In addition to tracheids, angiosperms possess vessel elements for transporting raw sap.
Answer:
They share two lone electron pairs
oxygen has 8 charges and hydrogen has 1 charge. Oxygen is negatively charged and hydrogen is positively charged.
The answer is; asexual reproduction
In specific, this type of asexual reproduction is called budding. In this type of reproduction, the offspring is completely identical to the parent and there is little room for variation as in the case of sexual reproduction. Other living organisms that exhibit this type of reproduction are yeast, bacteria, and protozoans.
Answer:
The answer is Brain Stem.
Explanation:
The brain part that we are least consciously aware of is the brain stem and the reason is because of how it operates and it's functions.
The brain stem is the part of the brain that is located at the end and controls the message flow between our body and our brain. It also regulates our physiological processes such as heart rate, blood pressure, breathing etc. without our notice.
I hope this answer helps.
Answer:
Size of the band varied
Explanation:
In the given question, the options are not provided but based on the information provided in the question, it can be predicted.
When the DNA was digested by the HindIII, then the length of the digest came about 1000 bp and the undigested DNA was also found 1000 bp.
When both the bands were analysed by Gel electrophoresis then the bands do not run to the same distance therefore this shows that the size of both the bands was not equal and their size varied.
Thus, the size of the band varied is correct.
